The PlayStation Camera provides facial recognition, motion control and video capture capabilities to the PS4.
With the Camera, PS4 can scan your face and log you into your user profile, once you set it up to do so. When you enable facial recognition in settings, the Camera will find and highlight your face on the screen and the console will take you through a few steps to record your face data. For optimal recording, you're advised to sit around 6 feet (1.8 meters) away from the Camera, to make sure there is ample light in the room (but no strong light behind you), that your hair doesn't touch your eyebrows, and that the lenses of the camera are clean and free of the protective film that ships affixed to them. It will then go through a calibration process that asks you to tilt, turn and nod your head in various directions. You can even go back later and add additional face data to your user profile under different conditions to increase accuracy, and the system allows face data for multiple user profiles. The information is housed on your PS4 and according to Sony it will not be shared.
But facial recognition isn't the only nifty feature. The device is able to use its dual cameras to perceive depth in the 3-D environment of your room and to capture 3-D images. Additionally, the DualShock 4 light bar lights up as a distinct color for each user based on the order the controller is connected. Player one is blue, two is red, three is green and four is pink. The PS Camera has the ability to recognize the color on the controller to help it pinpoint the position of each player in the room, taking the place of one of the functions of the previous Move motion controller, for still more accurate motion and location sensing.
PlayStation Camera also allows you to display your image on screen during game play and live-streaming, a feature you can find out more about in the next section.
